Institute reduces per-stone fee for synthetic and natural testing.

The Gemological Institute of America (GIA) has implemented a new, lower-cost fee structure for Quality Assurance (QA) services, offering tests to determine stone treatments, surface treatments and diamond type.

The QA service offers diamond tests in response to the increase in treated and synthetic diamonds in the marketplace. The GIA is now offering testing for loose and mounted diamonds in the smaller size ranges to help jewellers make determinations about items being offered to you.

The service is available for D to Z and coloured diamonds of 0.20 carats and less, and black diamonds of 5.00 carats and less.

The new fee structure reduces the existing per-stone fee from $12 (£7) to $10 (£6) for diamonds between 0.06 and 0.20 carats and to $5 (£3) for diamonds 0.05 carats and smaller, creating a more affordable screening option for clients.

The QA service is used to determine natural vs. synthetic stones and any colour and clarity treatments, diamond type, gem material and surface treatment.

Results from QA test are presented in a table format, with a Rush Service available subject to availability.
